Walkie-Talkie [SPOILERS]

I just replayed Episode 1, and I realized that the person who has been talking to Clem, has to of met Glen at one point, or at lease his car. When Glen left the motor inn in episode 1 he took the other walkie-talkie by mistake in his car.

I don't know if her talkie has it's own special frequency so it can only talk to the other talkie, making her think it is broken because she cannot talk to anyone on the other end, until someone finds the one in Glen's car. Or if this is a normal radio that can switch between multiple frequencies.

It looks like one of those simple household Fisher-Price toy walkie talkies, so how it has a range past 200 yards is a dark mystery
